I had the same problem, so i tried P2P trials and WoW was quite medicore and felt like quest grinding with no real reason why apart from to get to level 60 (without BC) and the level cap was even smaller because i was on trial. DDO is one of the best for RolePlaying but to many instances broke it. Now my personnal favourite was Lotro with a mix of the useally collect that item kill X of Y for exp but great instances for story (a story) i felt like i was in middle earth and actually achieving something.
Trial runs out soon so i'm gonna have to buy the game =).
